I've noticed that when I use a .45U Whattman syringe filter with a 21 guage needle and pass the finished compound thru it warm that the filter clogs after filtering 20ml of product(2 10 ml vials) & it is very hard on the fingers. Should I use an 18 gauge needle and a different size(maybe a 22ml Whatman filter) for easier filtering????
